这里使用JSF2.0技术实现中国行政区划管理,通过范例可以看到JadePool实现了与JSF框架和Primefaces的完美组合。本范例完整演示了以下操作:1、导入中国大陆行政区划记录,并将记录保存到数据库中;2、实现多功能的分页查询;3、在DataTable行中修改行政区划记录。数据来源于国家统计局于2012年11月份公布的中国大陆行政区划。这些数据被打包在jadepool-1.0-GBK.jar文件中,可以通过cn.jadepool.util.China的division()方法导出。
一、修改模板文件
1、将模板文件IndexTemplate.xhtml中的<p:menuitem value="行政区划" url="#" />修改为:<p:menuitem value="中国行政区划" outcome="cn_address" />,outcome指向本系统内的一个JSF页面文件,不需要文件的后缀名。
2、增加一个导航到首页的菜单项<p:menuitem value="返回首页" outcome="index" icon="ui-icon-home"/>,icon用来在菜单项前增加一个图标。
3、在底部布局中,增加一个消息提示组件<p:growl/>,需要在<h:form/>中添加。代码如下:
<p:layoutUnit position="south" size="40" closable="true" collapsible="true"> <h:form id="bottomForm" style="padding: 4px;text-align:center;"> ... <p:growl id="bottomGrowl" showDetail="true" /> </h:form> </p:layoutUnit>
修改后的模板文件见附件1。
二、创建AddressBean受管Bean
AddressBean受管Bean源代码见附件2。
AddressBean用来提供行政区划的数据,实现应用程序逻辑和业务逻辑。除了set、get方法外,其它的属性、方法均作了详细的注释。由于使用JadePool作为持久化工具,实现数据更新、查询的操作都非常方便。
三、创建中国行政区划管理页面
创建模板客户端网页文件cn_address.xhtml,源代码见附件3。
创建后,将文件的字符集编码修改GBK。
在cn_address.xhtml页面中实现了以下操作:
1、导入中国行政区划记录,并将记录保存到数据库中;
2、实现多功能的分页查询;
3、在DataTable行中修改行政区划记录。
导入的页面代码:
<p:commandButton style="float: left;" value="初始化地名" action="#{addressBean.reUpdateDiming}" icon="ui-icon-disk" update="@form :bottomForm:bottomGrowl"/>
导入实现的java代码:
/** * 导入中国大陆的行政区划 * * @return null 导航到指定的页面,null值代表返回当前的页面 */ public String reUpdateDiming() { Jade j = new Jade(); List<Map> v = cn.division(); for (Map m : v) { j.save("cn_address", m);//这是为了保护已经修改的成果 } dimingList = j.query("select * from cn_address"); dimingModel = new ListMapDataModel(dimingList, "addresscode"); j.commit(); FacesContext.getCurrentInstance().addMessage(null, new FacesMessage("导入地名", "导入地名记录" + dimingList.size() + "条!")); return null; }
分页查询的页面代码:
<p:dataTable id="addressDataTable" value="#{addressBean.dimingModel}" var="m" rowIndexVar="i" paginator="true" paginatorPosition="bottom" rows="10" paginatorTemplate="{CurrentPageReport} {FirstPageLink} {PreviousPageLink} {PageLinks} {NextPageLink} {LastPageLink} {RowsPerPageDropdown}" rowsPerPageTemplate="10,15,20,25,30,35,40,45,50,55,60" selection="#{addressBean.dimingSelected}" selectionMode="single" editable="true" > ......
在分页中调用的查询数据,如:
<p:column headerText="标准名称" style="width:15%;" sortBy="#{m.addressname}" > #{m.addressname} </p:column>
需要指出的是ListMapDataModel dimingModel数据模型是直接将JadePool查询结果转换而来的,而且可以直接在JSF的UI组件中调用,如:<p:inputText value="#{m.longitude}" />。将其修改后又能直接保存到数据库中,因此,极大地方便了JadePool用户。代码如:onEdit方法中保存修改的代码
Record r = new Record(); Map dm = r.one(this.dimingList, "addresscode", m.get("addresscode")); Jade j = new Jade(); j.save("cn_address", dm); //......
修改记录时的页面效果见图
